This exists.  I use it for the picture language, for example.  Here’s
the Guix definition:

--8<---------------cut here---------------start------------->8---
(define-public guile-picture-language
  (let ((commit "1531116036d1b5e0d2482ff2c8d77ad21f1d2bef")
        (revision "1"))
    (package
      (name "guile-picture-language")
      (version (git-version "0" revision commit))
      (source (origin
                (method git-fetch)
                (uri (git-reference
                      (url "https://git.elephly.net/software/guile-picture-language.git")
                      (commit commit)))
                (sha256
                 (base32
                  "04salmqf5x84vb3qkkxx47b64jyl290zsf3ik81l9hg6fwvvlmq3"))))
      (build-system guile-build-system)
      (inputs
       `(("guile" ,guile-2.2)))
      (home-page "https://git.elephly.net/software/guile-picture-language.git")
      (synopsis "Picture language for Guile")
      (description
       "This package provides a simple SVG-based picture language for Guile.
The picture values can directly be displayed in Geiser.")
      (license license:lgpl3+))))
--8<---------------cut here---------------end--------------->8---

This takes care of compiling the files and placing them where they
should go.  The upstream picture language repository does not use
Autotools.
